Description

The present invention relates to a radiographic imaging device for the type of limb specified in the preamble of claim 1. In particular, this device is suitable for use in the medical range to acquire images of the human lower limbs and in the veterinary range to acquire images of the forefoot and / or hindfoot.

Currently known radioimaging devices include gantry and support structures for patients. The gantry has an annular casing centered on an analytical area, within which sensors and sources, various source motion and control members, and detectors are located. The support is a horizontal platform on which the patient lies and is suitable for placement in the analytical area, allowing the limb to be placed in that area and thus between the source and detector. Is.

The above prior art has some serious drawbacks. The first drawback is that it is essentially impossible to tomography or other imaging of only the extremities at any angle. In practice, both limbs of the patient are located within the analytical area, and therefore rotation of the source and detector forces the acquisition of images of both limbs.

To solve this problem, support components have been designed that allow only the limb to be analyzed while leaving the other limb outside the gantry, or allowing the limb to be placed in a different position.

Swiss Patent No. 6923378, US Patent Application No. 2011/23, 1995, and US Pat. No. 6,378,149 provide examples of such supports.

While such supports reduce drawbacks, optimal and complete acquisition of the limbs is not possible. These can be used almost exclusively in the range of human medicine, but not in the range of veterinary medicine, and most importantly, for large or medium sized horses or other animals. Can't. In practice, the weight and size of these animals creates considerable difficulty in placing them on the support, often with the use of sedatives that put the animals to sleep, and cranes or other means of moving the animals. Requires both use of.

Another drawback is determined by the fact that these supports place the patient's limbs unnaturally and are uncomfortable to maintain during the entire acquisition time. This drawback is especially evident in tomography, where repeated limb movements are required for acquisition due to its long duration.

Another serious drawback inherent in all of the above devices is that the device cannot be carried due to its large size and therefore the animal must be taken to the appropriate facility.

In addition, the control station includes a casing that defines the outer surface of the control station. The control station may have at least one fitting that constrains the first and second modules and a connecting member of the platform to the casing.

In the structural sense, the functions of the radiographic imaging device for the limbs described above are as follows.

First, the operator commands the connecting member 55 to rotate the platform 7 mounted on the floor surface 1a through the interface means 51 to place the limbs 10 to be analyzed on the platform 7. It should be noted that the patient, who is a human or animal, can be placed upright on the platform 7 and thus on the surface 7a to walk. For example, in the case of a horse, the operator advances the animal and guides its forefoot 10 to the analysis area 7c.

Specifically, to optimize the analysis, the operator places each limb 10 in the ascending portion of region 7c to ensure that the vertical axis of gravity 10a is essentially centered in central analysis C. To do. At this point, the operator removes the modules from the station 5, places them on the surface 7a at the openings 7d and 7e, converts them into a drive unit 4 on the conveyor 74 by the control station 5, and converts the rotating shaft 4a into a drive unit 4a. Command the center of the analysis center C, and therefore the vertical axis 10a of the limb 10 being analyzed. The operator again commands the command station 5 to move the attachments 8 and 9 to the engaging position and thus constrain the sliders 41 and 42 to the modules 2 and 3. In this regard, the operator selects the type of radiographic imaging to be performed (eg, computerized tomography), the extension of the portion of the limb 10 to be analyzed along the axis 10a, and the emission / acquisition parameters. After setting the acquisition, radioimaging begins automatically or in response to a command given by the operator via means 51. The sliders 41 and 42 slide on the guides 45 and 46 to guide the modules 2 and 3 to the acquisition start position by arranging the second module 3 between the limbs 10. At the same time, the transducers 22 and 32 move the source 21 and the detector 31 along the axes 22a and 32a, guiding them to the correct height of the limbs 10. After the positioning of the source 21 and the detector 31 is complete, the source 21 penetrates only the limb 10 under investigation and emits radiation that hits the detector 31, while the sliders 41 and 43 have axes 4a and 10a. By rotating modules 2 and 3 around the limb 10, the limb 10 completes the acquisition, and the image representation of the image can be acquired.

Subsequently, if the operator wishes to perform, for example, a linear X-ray examination, he sets the emission / acquisition parameters so that the device 1 starts radioimaging automatically or in response to the instructions given by the operator. To do. In this case, the sliders 41 and 42 guide the modules 2 and 3 to the desired positions, and the source 21 penetrates only the limb 10 under investigation and emits radiation that hits the detector 31. At the same time, the transducers 22 and 32 move the source 21 and the detector 31 along the transform axes 22a and 32a essentially simultaneously to perform the acquisition along the entire length of the region of interest. Finally, if the animal moves one of its limbs on the surface 7a during these movements, a movement sensor detects the movement and transfers attachments 8 and 9 to at least the release and release positions through station 5. It should be noted that it orders the suspension of.

The connectors 61, 62, and 63 are identifiable in hollow contours and each have its own data transmission and / or power cable. In this case, the rotary joints 64 and 65 may provide one or more slip contacts (or slip rings) suitable for connecting the cables of the static connector 61 to those of the rotary connectors 62 and 63. .. Each of these sliding contacts is generally integrated with one of the rotating connectors 62 or 63 and consists of a rotating conductive ring suitable for rotating around the rotating shaft 4a.

In this embodiment, the connecting device 6 provides an antenna integrated with the second module 3 and an additional antenna associated with the station 5.

In the structural sense, the functions of the radiographic imaging device for the limbs described above are as follows.

First, the operator instructs the connecting member 55 to rotate the platform 7 mounted on the floor surface 1a through the interface means 51, and places the limbs 10 to be analyzed on the platform 7. It should be noted that the patient, who is a human or animal, can be placed upright on the platform 7 and thus on the surface 7a to walk. For example, in the case of a horse, the operator advances the animal and guides its forefoot 10 to the analysis area 7c. In certain embodiments, in order to optimize the analysis, the operator places each limb 10 in the ascending portion of region 7c to ensure that the vertical axis of gravity 10a is essentially centered in central analysis C. To. At this point, the operator may remove the modules from the station 5 and place them on the surface 7a at the openings 7d and 7e. Then, using the control station 5, the operator transforms the conveyor 74 into a drive unit 4 and places the rotation axis 4a in the center of the analysis center C, and hence the axis 10a of the limb 10 being analyzed. Order. The operator contacts the command station 5 again and commands the transfer of the attachments 8 and 9 to the engaging position, and thus the restraint of the sliders 41 and 42 to the modules 2 and 3. In this regard, the operator selects the type of radiographic imaging to be performed (eg, computerized tomography), the extension of the portion of the limb 10 to be analyzed along the axis 10a, and the emission / acquisition parameters. After setting the acquisition, radiation imaging begins automatically or in response to a command given by the operator via the interface 51. The sliders 41 and 42 slide on the guides 45 and 46 to guide the modules 2 and 3 to the acquisition start position by arranging the second module 3 between the limbs 10. At the same time, the transducers 22 and 32 move the source 21 and the detector 31 along the axes 22a and 32a, guiding them to the correct height of the limbs 10. After the positioning of the source 21 and the detector 31 is complete, the source 21 penetrates only the limb 10 under investigation and emits radiation that hits the detector 31, while the sliders 41 and 43 have axes 4a and 10a. By rotating modules 2 and 3 around the limb 10, the limb 10 completes the acquisition, and the image representation of the image can be acquired.

Subsequently, if the operator wishes to perform, for example, a linear X-ray examination, the operator sets emission / acquisition parameters and the image forming device 1 forms a radiographic image automatically or in response to an instruction given by the operator. May be started. In this embodiment, sliders 41 and 42 guide modules 2 and 3 to desired positions, and source 21 penetrates only the limb 10 under investigation and emits radiation that hits the detector 31. At the same time, the transducers 22 and 32 move the source 21 and the detector 31 along the transform axes 22a and 32a essentially simultaneously to perform the acquisition along the entire length of the region of interest. If the animal moves one of its limbs on the surface 7a during these movements, a movement sensor detects the movement and orders at least release and interruption of metastasis to the release position through control station 5. Can be considered.

With reference to both descriptions of radioimaging device 1, the present disclosure achieves important advantages. The first advantage is the ease of positioning of the human or animal patient guaranteed by defining the support surface 7a. In practice, with the exception of modules 2 and 3, the support surface 7a is free and therefore almost completely accessible for patient positioning. This advantage is dictated by the innovative creation of the outer surface 7a, where modules 2 and 3 and the inner housing 7a representing an environment different from that of the positioning of modules 2 and 3 are mounted. The unit 4 and later the device 6 are arranged inside. This advantage is further exacerbated by the fact that modules 2 and 3 are passive, i.e., lacking a motor or other drive device, especially along the outer surface 7a of smaller dimensions.

Another advantage of the platform 7 over the control station 5 is that it reduces the overall dimensions of the radioimaging device 1 and allows the entire working radioimaging device 1 to be moved from a single control station 5. , And given by the constraints of modules 2 and 3. As a result, the radiographic imaging device 1 is simple and convenient for transport to a stable location or other location that was difficult to access with prior art devices.

Another advantage is the presence of motion sensors that separate the sliders 41 and 42 from modules 2 and 3 and release them from platform 7 by detecting the motion of the limbs 10 mounted on platform 7. .. As a result, a possible collision of the limb 10 with one of modules 2 and 3 does not injure the animal or damage modules 2 and 3. This advantage is further ensured by the fabrication of the casings 24 and 34 of the braking material, which can absorb the impact and avoid damage to the equipment inside the module.

Modifications of the invention may be made within the concept of the invention as set forth in the independent claims and by relative technical equivalents. All details may be replaced with equivalent elements and materials, shapes and dimensions as required.

The housing slot of the slider 41 to be arranged may be defined. The first engine 43 may also include a rack built on the first slider 41 and powered jagged wheels connected to the carrier 742 and engaged with the rack. Similarly, in one embodiment, the second slider 42 may be identified in at least one ring region. A second guide 45 provides one or more unused pins that are hinged to the carrier 742 and is spaced apart from the carrier 742 to hold the slider 42 that rises from the carrier 742. The housing slot of the slider 42 of 2 may be defined. The second engine 43 may include a rack built on the second slider 42 and powered jagged wheels connected to the carrier 742 and engaged with the rack.
